sigh so many people using hybrids and they don't know what they are doing with them.
I have the copper smpl and copper praxis and never had a problem with them.
as long as the 510 connector sticks out by about 2millimetres from the Threads on the bottom of the atty there wont be a problem.
I don't use attys with less than 1.5mill sticking out
Good on you. Now I know. Thank you.
